Fig. 6 a sectional view on the line 6-43 V This invention relates toimprovements in latches for vehicle doors, and particularly to latchesfor this purpose which are provided with means for locking thelatch-bolt "in its thrown position. The latch-bolt is usually retractedby the well known pivoted lever or rotary lever. In some vof my priorpatents the locking means for the latch bolt is actuated by a.push-button and associated parts carried by the operating lever, whetherof the pivoted or rotary type,

' and projecting from the upper end thereof. Examples of such structureswill be found in Patents 1,415,839 of May 9,1922, 1,453,712 of a May 1,1923, and 1,551,032 of August 25,.

- 1925, Reissue 16,735 of September 13, 1927.

The general object-of the present invention is to' provide lockactuating means independent of the operating lever but 40 projectingupwardly from thelatch struc- .tnre t0 a. convenient position adjacentthe said operating lever, in conjunction with means for automaticallyreleasing the latchbolt when the operating lever is manipulated to openthedoor.

' A contributory object is to provide 'an arrangement of two levers, oneoperated by a vertically arranged push-r0d to throw the other lever intoposition to lock the bolt,

J said other lever being moved out-of its locking position whenever thedoor is opened from the inside.

Other ob'e'cts relate to features of.-construotion'w ch will beapparentfrom' the ing' my invention, operated by a vertically 'tion tobe 0 following description of one embodiment of the invention. i

In Fi s. 1 and 2 of the drawings, I have shown the invention as appliedto a'latch for vehicle doors operated by a. pivoted vor swinging lever.Incarrying out my invention, I employ the usual latch-bolt 10, normallythrown forward by a spring 11, and

adapted to be engaged for rearward move ment by a lever 12 extendingupward through the door and provided at its upper end with a. handle 13.The bolt is provided with theusual upward projection 14 extending intothe path of a. roll-back 15, which, in the present instance, extendsupwardly from the usual square shaft (not shown) and is adapted to beoperated by a handle on the outside of the door. Pivotally mounted abovethe'bolt is a locking-lever 16, the nose of which is adapted to beturned'into the path of the roll-back 15. At its rear end, this lever isformed with a cam-lip 17 adapted to be 'engaged by a. stud 18 mounted inthe lever and travelin in a segmental slot 19. lEivotally mounte on thecase-plate, above and forward of the locking-lever 16, is a push-buttonlever 20, formed witha lip 21 adapted to bear upon the upper edge of thelockinglever 16, and with a lip 22 at its rear end in line with avertically arranged push-rod 23, which is mounted in the case closelyadjacent to the lever 12, and in convenient posiforcing the push-rodlever 20 downward,

causing the hgfl' to engage with theedge 16 of the loc rated from theinside of a car.

g-lever and force it down into the path of the roll-back 15. T 0 movethe locking-lever out of its locked position, the lever 12 is movedrearwardly whereupon the stud 18 engages with the lip 17, so as to:

depress the rear end of the locking-lever and lift its forward end outofthe path'of movement of the roll-back. =At the same time, this upwardmovement of said end lifts the push-button lever and with it the'pushrod 23, so that it is in'position for relocking the door whendesired.

In Fig. 5 of the drawings, I have shown" my invention as applied to a.well known ro- Iever form of vehicle door latch, in

.wluch the bolt is operated by a verticall arstewardess. o H. I

setovcr the spindle 24 and are provided at their ends with slots29 whichset over 'projcctions 30, which are struck up from the latch-plate andupsetto lock the straps in position. The term inside refers to thesurface of the case-plate visible in Figs. 1

' and for example, although when the struc ture is applied to anautomobile door, the

',opposite,side of said face-plate becomes part bf'the inside surface ofthe door, as will be apparent from Fig. 6, wherein the bevel on the endof the latch-bolt is clearly shown, --The front end of the structure, asdescribed, is the end from which said beveled latch-bolt projects.

What I claim is: a v

1., A latch, comprising a bolt, a lever for retiringsaid bolt,-,.aroll-back adapted-to retire said bolt, a locking-lever pivoted above thebolt'and extending into the path of the locking-lever pivoted above thebolt and exroll-back', a push-rod lever pivoted at one end, above andforward of the locking-lever, a push-rod mounted in line withand'bearing upon'the push-rod lever and adapted, when forced down, todepress the forward end of the locking-lever, and means for depressingthe rear end of the locking lever to lift it out of the path of theroll-back and to raise the push-rod. I 2. A latch, comprising a bolt, aswinging lever for retiring said bolt formed with a projection, aroll-back adapted'toretire said bolt, a locking-lever pivoted above thebolt and extending into the path of the roll-back,

a push-rod lever pivoted at. one end above and forward of thelocking-lever and' adapted, when forced down, to' depress the for-' wardend of the' locking-lever, the rear end of said locking-lever extendinginto the path of the projection on the swinging lever.

3..-A latch, comprising a bolt, a lever for retiring said bolt formedwith a projection,

a roll-back adapted to retire said bolt, a

-tending into the path of the roll-back, and "into the path oftheprojection on the boltlever, a push-rod lever pivoted at one end and:forward of the locking-lever and formed with .a lipiadapted to engagewith the upper sF-edgeof the-'locking-lever andfwith a second --lip1,-ga-push-rodi inposition to engage said a6 -seeondT li-p.,' the'srear endof the locking-lever being formed with a. cam-surface adapted to be enaged by said projection on the lever, where by, when the lever isturned, the rear end otthelocking-lever will be depressed and theforward end lifted out of the path of the roll-back.
